| Research Abstract |
The relationship between mechanical stress and osteogenesis has been widely studied. However, little is known about the functions of the periosteum in bone remodeling under mechanical stress. We hypothesized that the periosteum senses a mechanical stress to induce bone remodeling, therefore, we subjected periosteum cells to load mechanical stretching and characterized their gene expression profiles.
Periosteum cells appear to induce, in response to the stretch stimulus, gene expression changes in WNT pathway and BMP pathway, which cooperate to promote osteoblast differentiation and osteogenesis. Our results also suggest that during mechanical stress-induced bone remodeling in the body, the periosterum senses the mechanical stress to control signals for promoting osteoblast differentiation and osteogenesis.
